How to get a smoothg riding F250/350

I have recently done a suspension modification to my trucks rear spring pack.
I cut out a plate from 3/8 steel the same size as the factory shim for the spring packs. I placed it above the overload spring and at the same time extended the spring alignment tabs another 1/2 so it will still keep the springs from walking around sideways.
I have taken some pictures of the work to show how it was done.

The ride is great I have been driving it this way for a few weeks now and love it. It no longer gallops down the highway and the ride quality is hard to believe.
I know the rear will sag much sooner with less weight but I am not concerned because it rode the bumpers when it was full of firewood before.
Ride is better than my wife's 2002 Tahoe.

Did you lose any rear ride height?

This dropped your payload capacity severely.

Nice idea. If you wanted to increase your payload capacity again, you can install a set of air bags.

So basically all you did was remove a leaf from your springs because that spacer is basically making the bottom leaf pretty much useless. Couple issues. First - there is no longer any support for the spring pack so there is nothing protecting it from being forced into a reverse curve which is not good because by the time the upper leafs contact that lower leaf its too late. Second - now that you have a softer suspension your making your truck handle worse. If you want a better riding and a safe riding safe truck I would talk to someone that really knows suspensions like Cary at CT Performance Inc who is a supporting vender and does wonders with making Excursions ride 100% better.

When I load the truck heavy with firewood it rides the bumpers tight. It will not go any lower then the bumpers for max travel.
Yes the load capacity is lower but it hits the overload at 2-1/2" of travel and starts taking the load from there till the bumpers.
I run empty 99% of the time so for me it's pure bliss and the bumper will only allow the maximum designed deflection.
That hunka chunka of overload spring is determining the ride in the rear. No shocks of any design can overcome it's values. A completely different spring pack is another story.

Not for everyone but for my empty truck it's awesome.

It does not drop the payload, I loaded truck with oak firewood two weekends ago and it settled faster but once spring pack hit the overload it loaded out the same. It never hit the bumpers so I know it's the same as before.
This mod works, only real downside I see is truck settles faster with moderate load. But once I get around a thousand pounds it's into the overload and loads out the same.
Cheers

It did drop the payload. Looking at a the leaf pack you now only contact the overload on the furthest edges (least strength). It should be contacting the entire length of the overload. Really its very simple leverage/physics.
